Read the given statements and conclusions carefully. Assuming that the information given in the statements is true, even if
it appears to be at variance with commonly known facts, decide which of the given conclusions logically follow(s) from the
statements.
Statements:
Some bags are purses.
All purses are wallets.
All wallets are sacks.
Conclusions:
(I) All purses are sacks.
(II) Some wallets are bags.
Both conclusions (I) and (II) are follow
Only conclusion (II) is follow
Neither conclusion (I) nor (II) is follow
Only conclusion (I) is follow
Correct answer
Both conclusions (I) and (II) are follow
Why this answer is correct
The least possible Venn diagram for the given statements is as shown below :
Conclusions:
I. All purses are sacks → Follow (As some bags are purses, all purses are wallets and all wallets are sacks. As whole purses comes in wallets which whole comes in sacks, therefore it is true.)
II. Some wallets are bags → Follow (As some bags are purses and all purses are wallets. As whole purses comes in wallets and has some part common with bags, therefore it is true.)
∴ Here, Both conclusions (I) and (II) are follow.
Hence, "Option 1" is the correct answer.
Three statements are given, followed by three conclusions numbered I, II and III. Assuming the statements to be true, even if
they seem to be at variance with commonly known facts, decide which of the conclusions logically follow(s) from the
statements.

All sofas are benches.
All tables are sofas.
Conclusions:
I. No table is a chair.
II. Some sofas are chairs.
III. All tables are benches.
Only conclusion I follows
Only conclusions I and II follow
Only conclusion II follows
Only conclusions I and III follow
Correct answer
Only conclusions I and III follow
Why this answer is correct
The least possible Venn diagram for the given statements is as shown below :
Conclusions:

Three of the following number-pairs are alike in some manner and hence form a group. Which number-pair does not belong
to that group?
(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent
digits. E.g. 13 – Operations on 13 such as adding/subtracting/multiplying etc. to 13 can be performed. Breaking down 13 into
1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)
21 – 420
22 – 462
18 – 306
15 – 240
Correct answer
15 – 240
Why this answer is correct
The logic followed here is:
Option 1) 21 – 420
212 - 21 = 420
441 - 21 = 420
420 = 420 (LHS = RHS)
Option 2) 22 – 462
222 - 22 = 462
484 - 22 = 462
462 = 462 (LHS = RHS)
Option 3) 18 – 306
182 - 18 = 306
324 - 18 = 306
306 = 306 (LHS = RHS)
Option 4) 15 – 240
152 - 15 = 240
225 - 15 = 240
210 ≠ 240 (LHS ≠ RHS)
Thus, out of all the options, '15 – 240' is the odd one out.
Hence, "Option 4" is the correct answer.

The logic followed here is:
Logic: (1st number × 2) + 1 = 2nd number.
Now,
For 12 : 25:
⇒ (12 × 2) + 1
= 24 + 1 = 25.
For 11 : 23
⇒ (11 × 2) + 1
= 22 + 1 = 23.
Similarly, for Option 3: 21 : 43
⇒ (21 × 2) + 1
= 42 + 1 = 43.
Hence, the correct answer is Option 3.
Identify the figure given in the options which when put in place of ? will logically complete the series.
Correct answer
Why this answer is correct
The logic followed here is:
Letter element shift to the right side back and forth.
Alternately letter element is replaced by letter element subsequently.
No specific pattern is followed here for the alphabet element series, as it can be seen clearly that the letter element is replaced by new letter element randomly but no previous letter element used is repeated.
2) Digit element series →
Digit element shift to the left side back and forth.
Alternately digit element is replaced by digit element subsequently.
Thus, the final series is:
Hence, "Option 1" is the correct answer.
Additional InformationOption 1) It has new letter element after replacement i.e. not used previously in the given series and follows the other pattern too in the series.
Option 2) It has new letter element after replacement i.e. not used previously in the given series but doesn't follows the other pattern in the series (Letter element should be in the center), therefore is eliminated.
Option 3) Thought is follows the pattern of the whole series but the letter element after replacement is repeated i.e. already used in the given series, therefore is eliminated.
Option 4) It doesn't follows the pattern of the whole series (letter element should be in the center) and also the letter element after replacement is repeated i.e. already used in the given series, therefore is eliminated.

(25, 300, 6)
(19, 342, 9)
(17, 476, 7)
(24, 600, 5)
(18, 288, 8)
(14, 364, 7)
Correct answer
(18, 288, 8)
Why this answer is correct
The logic followed here is:
(25, 300, 6)
25 × 6 × 2 = 300
300 = 300 (LHS = RHS)
And,
(19, 342, 9)
19 × 9 × 2 = 342
342 = 342 (LHS = RHS)
So, checking each option one by one:
Option 1) (17, 476, 7)
17 × 7 × 2 = 476
238 ≠ 476 (LHS ≠ RHS)
Option 2) (24, 600, 5)
24 × 5 × 2 = 600
240 ≠ 600 (LHS ≠ RHS)
Option 3) (18, 288, 8)
18 × 8 × 2 = 288
288 = 288 (LHS = RHS)
Option 4) (14, 364, 7)
14 × 7 × 2 = 364
196 ≠ 364 (LHS ≠ RHS)
Thus, out of all the options, '(18, 288, 8)' follows the same logic as given.
Hence, "Option 3" is the correct answer.

Six letters A, T, M, P, S and R are written on different faces of a dice. Two positions of this dice are shown in the figure below. Find the letter on the face opposite to the one having R.
S
T
A
M
Correct answer
M
Why this answer is correct
The logic followed here is :-
From the given two different cubes the adjacent sides are as shown below :
As M is common on both the dices, it is clear that T, A, P, and S are adjacent to it, and the remaining i.e. R will be opposite to it.
Opposite pairs:
T → P
A → S
M → R
So, the opposite side of "R" will be side "M".
Hence, the correct answer is "Option 4".
